Quercetin Working at its Fullest Potential

While quercetin is well-known for its potential to support a healthy immune response, respiratory function, and healthy histamine levels†, the fat-soluble flavonoid can also be difficult for the body to absorb.*GammaSorb™ graphic

That’s why this product features our exclusive GammaSorb™ delivery system. GammaSorb is a plant-based material that binds to nutrients, making them more easily absorbed and bioavailable for optimal benefits. It helps deliver a higher level of support for your overall health.*


Synergy that Delivers for Immune Support *

Vitamin C can also aid in quercetin absorption, making it even more effective, and it is a key nutrient for healthy immune function.*

Frequently Asked Questions

How does GammaSorb™ work?

GammaSorb (gamma-cyclodextrin) could be compared to a microscopic bucket, scoop, or other container that carries fat-soluble ingredients through the walls of the intestines as though those ingredients were water soluble. It’s almost like having a water-soluble shell that surrounds a fat-soluble nutrient to protect it just long enough for it to be absorbed.

What is the source of quercetin in this formula?

Quercetin is widely available from many foods, including onions, apples, tea, berries, and grapes. However, there are many other botanical sources, such as the flower buds from the Japanese Pagoda Tree (Sophora japonica), which provide the quercetin used in this formula.
